Prehistoric man ate much healthier diet

To figure out how we should be eating to stay healthy, it is useful to look back to life in the preagricultural (Paleolithic) era. Fossil remains from humans who lived 10,000 to 40,000 years ago show that although many people did not live to old age (because of their dangerous environment with no medical treatments) the people who made it to old age appear to have been healthier than we are today. They were even slightly taller on average than we are today, which indicates that they were well nourished.
